S2 Exhaust Flexi Pipe

22 posts in this topic

I wish I knew that Brian when mine went. The stainless replacement is dear and it's not a last forever part cos the flexi will go again at some point. Welding a new bit in seems like a good plan.

trick is to do it before it is too knackered, once it falls in two you need to be able to offer it onto the car to get the relationship of the two pipes correct. If you get it while it still hangs together, then you can lay it in a piece of angle iron, tack weld it to maintain the relationship/length, then cut out the old flexi and weld in the new one, then cut it off the angle iron and weld the back which would have been obscured whilst it lay in the angle iron.

 

there are good and bad replacement flexis, the better ones have an inner spiral wound section which carries the heat as much as anything (it isn't gas tight) then there is a bellows section (which is gas tight but isn't great with high temps) and finally the outer braid. most are stainless anyway, but the poor quality ones don't have the inner spiral wound section so the heat makes the bellows go brittle and crack quite quickly.

 

the last one i got from this vendor http://www.ebay.co.u...cat=0&_from=R40 and the quality was top notch - especially for the money, quick delivery too if i remember correctly.

Thanks for the info guys. Btw I have a 2002 elise s2

Brian, do you know what size flexi to buy from the eBay link?

 

On another note Dean, what is our stock piping size 2.25" or 2.5" , I'm planning to get a hi-flow cat and single exit side muffler.

I was looking at purchasing either the boe silent touch 2.5" (it's for I'm guess 2005 onwards as USA didn't offer rover-k)

Or 2bular, which offer 2.25" the website states you lose torque if you go bigger than that on a rover.

 

Thx

Off the top of my head I'm afraid I don't, probably 2" and 200 long if I were to guess, though it may be bigger diameter.

they're easy enough to measure, but have to get the undertray off.

I don't know the diameter sorry. If you need/want the flexi pipe, cat and back box have you thought about getting a full system from Jim Valentine at 2bular? including manifold?

I would give him a ring. He is very helpful apparently and I only hear good stuff about his products.

At this point, im thinking a cut and replacement job for the flexi will be feasible.

I'm based in Australia, shipping alone is very dear not the mention our currency has turned to shit.

hmmm.

I hear Jim makes quality exhausts (although i also hear the occasional timely email responses/shipping issues)

      Evening fellow Lotuser's.
      ### The Story ###
      A few weeks ago my 2000 95K K-Series S1 Elise died of head gasket failure. I stripped it down intending to replace H/G (and all the other gaskets), h/bolts, c/belt + cam seals, w/pump, valve seals, ETC. As such I bought all the above new and spent about £120 in the process.
       
      I bought all this as I thought if I'm going to do this, I'm going to do it once and once properly. With this attitude I started getting prices on skimming the head and having it ported, valves re-seated ETC so it was worth putting it back on, there shouldn't have been a warped issue as it never ran over-heated. This all came to a few more hundred and I then started thinking well if I'm going to spend this much I should start looking into better way to spend the money and get more power... after a lot! of Google and head-scratching I decided on a VVC conversion for a cost/BHP+torque gain. Buying a bodywork/chassis knackered VVC MGF was cheaper than a VVC engine on it's own. So here's where I'm at
      In my Elise at the moment I have a very very clean, perfectly running non VVC 1.8 bottom end and gearbox with 95K miles on it. Next to it I now have a 68K miles VVC complete engine and gearbox covered slightly here and there in oil. I've never heard this engine/gearbox run but been assured it's 100%. The oil is very clean, the gear linkage moves freely and the expansion bottle is spotless. The coolant was beautifully florescent green while pissing out everywhere as I took it out of the MG I bought. The handbrake travels only one click, the wiper washer fluid is blue and the brake pads and discs are in very good condition as it seems this car was very well serviced.
       
      ###The Question ###
      My dilemma is:

      1) Do I remove what's left of my Elise engine and replace it for the entire slightly leaky paired VVC engine/gearbox as a one? Meaning the need to hire a hoist and then deliberating whether to strip the head off, change the h/gasket, c/belt, w/pump, seals, sort any leaks... ETC, so pretty much back where I started with additional costs as I believe a lot of the stuff I've already bough isn't useable on the VVC (non VVC head bolts, cam-belt + pulley, h/gasket)

      2) Rebuild my current bottom end with the VVC head meaning I can change the H/G and all other bits without effectively adding to my workload (bar the wiring harness!) but ending up with a bottom end and gearbox carrying 95K miles instead of 68K.
       
      Is there any advantage to keeping the VVC bottom end and gearbox matched with the VVC head? Is the MGF VVC PG1 gearbox the same ratio's as the Elise 1.8 non VVC?

      Any thoughts appreciated
